Tex going below page bottom

I have been writing documents in Latex for a while, but this never happened to me before. I have a page with some text, images (with subfloats) and a table, and what happens is that the page doesn’t end where it should. In other words, some text and table go below the page limit. This seems somewhat related to the table itself, since everything goes back to normal if I remove the table. However, it’s almost the same table format that I have everywhere else, I just modified the text inside it.

I have reported an image showing the issue and the code related to the table. I don’t know if this can help, but I am using TexStudio with xelatex as compiler.

Any help would be appretiated, thank you.
